Bug#11657 Creation of secondary index fails:

  If TINYBLOB key part length is 255, it is equal
  to field length. For BLOB, unlike for CHAR/VARCHAR,
  we should keep a non-zero key part length, otherwise
  "BLOB/TEXT column used in key specification without a key length"
  error is produced afterwards.
